Double what xausa said. Some published/old loads are well over 60,000 PSI. Also some loads that might be fine in Harvey's latest long body, long neck version might not be fine in the original short body one. Oddly enough, the old reloading manual published by Herter's has pressure tested loads. Mine shoots half inch groups with any number of loads.
